@Susan3448 Unless the bulk of your reservations are long-term, or there are laws in your area about only renting for 30 days or more, I would suggest that you change your availability setting to a 2 week maximum. That should be enough even for people who are relocating and looking for permanent housing, and then even if those people find they need more time, and you have experienced them as good guests, you could always agree to extend the reservation.
You could also write in your listing more or less what you've written here, that your place is suitable for guests who are visiting the area, attending an event, or passing through, and will be out and about and busy the bulk of the time and that it is not suitable for those who have nothing to do and will just hang around the house all day.
Many hosts will ask a guest in an initial message when the guest sends a request, what brings them to the area. Of course, a guest can misrepresent their intentions and there's not much you can do about that, and some guests are even in denial about what kind of person they really are. I recall reading a post here from a host who said a guest portrayed themselves in their profile as being really sporty and liking to be out doing athletic things, but in fact, almost never left the house. The guest probably liked to think of themselves as being an active person, but really wasn't.
